The Vanishing (Harlequin Intrigue Series #1386)

Certain death awaits any outsider who enters Cache, a mythical city said to disappear when intruders threaten. But P.I. Max Duhon won't let the Cajun superstition stop him from going there. He'll do anything to help sexy Colette Guidry and close this missing person's case, even admit how attracted he is to his client. But as their investigation deepens, Max finds himself protecting Colette from the inexplicable terrors of the bayou. This includes the specter taunting them with voodoo…and a shotgun. It seems they may have come too close to Cache and its eerie secrets—and dangerously close to each other.
